       240-pin DIMM, DDR2-PC5300, 3-3-3-12, UNBUFFERED, NON-ECC, DDR2-667,
         2.2V, 128Meg x 64.
       The Ballistix line is specifically built for performance enthusiasts
        who want to push the performance envelope without worrying about
        data loss or corruption, mysterious intermittent errors and display
        problems, or worse -- the dreaded BSOD! The Ballistix line of high-
        performance memory modules features advanced speed grades, low
        latencies, and integrated aluminum heat spreaders.
       A Ballistix dual inline memory module (DIMM) consists of a number of
        memory components that are attached to a black printed circuit
        board. The gold pins on the bottom of the DIMM provide a connection
        between the module and a socket on a larger printed circuit board.
        The pins on the front and back of a DIMM are not connected to each
        other.
       Ballistix 240-pin DIMMs are used to provide DDR2 SDRAM memory for
        desktop computers. DDR2 is a leading-edge generation of memory with
        an improved architecture that allows it to transmit data very fast.
        Ballistix 240-pin DIMMs are available in DDR2 PC2-4200 SDRAM (DDR2
        533), DDR2 PC2-5300 SDRAM (DDR2 667), and DDR2 PC2-6400 (DDR2 800).
       To use DDR2 memory, your system motherboard must have 240-pin DIMM
        slots and a DDR2-enabled chipset. A DDR2 SDRAM DIMM will not fit
        into a standard SDRAM DIMM socket or a DDR DIMM socket.
       The number of black components on a Ballistix 240-pin DIMM can vary,
        but it always has 120 pins on the front and 120 pins on the back,
        for a total of 240. Ballistix 240-pin DIMMs are approximately 5.25
        inches long and 1.18 inches high, though the heights can vary.
        While 240-pin DDR2 DIMMs, 184-pin DDR DIMMs, and 168-pin DIMMs are
        approximately the same size, 240-pin DIMMs and 184-pin DIMMs have
        only one notch within the row of pins. The notch in a 240-pin DDR2
        DIMM is closer toward the center of the module.
